Description

A reinforced flame-proof panel

The present invention relates to a reinforced non-flammable panel for building, in particular, foamed pearlite foamed by processing the pearlite ore, hemp fibers giving a high tensile strength, gypsum powder giving a high compressive strength, and fillers The present invention relates to a reinforcing non-combustible panel having a panel filler which is dried and cured after compression processing of the mixture in a molding mold by mixing the loess serving as an adhesive of the present invention. Such a reinforced non-combustible panel has high tensile strength and compressive strength, as well as improved adhesion of panel fillers, thereby providing a high strength panel. In addition, the reinforcing fabric coupled to the panel filler is partitioned into several areas to prevent the panel filler from being excessively deformed by external lateral pressure, especially when the outer panel is used by combining the outer panel outside the panel filler, When the outer panel and the panel filler are stretched by the lateral pressure, the reinforcing cloth prevents excessive stretching of the panel filler so that the panel filler is not separated from the outer panel.

In general, a widely used building panel is used as a filler, and various materials such as flame retardant synthetic resin fiber, foamed resin board, stone, glass fiber, outer panel, loess, ceramic material, cork, gypsum, and the like are used as the filler.

In particular, building panels using organic materials mixed with foamed resins are widely used to improve insulation and sound absorption, have low hygroscopicity, and workability. Examples thereof include foamed polystyrene and foamed polyurethane, which are chemically synthesized styrofoam. , Expanded vinyl chloride, and other plastics.

However, such organic building panels are weak in heat and do not delay the collapse of the building, and thus have a disadvantage in that they cannot get time for fire suppression and have a weak strength. They cannot be used independently and must be used in combination with other materials. There is this. In addition, in the event of a fire, toxic gases are emitted, causing a lot of casualties, and as the time passes, the material of the filler deteriorates and the functions of insulation, sound insulation, etc. are deteriorated. It has the problem of environmental pollution.

Therefore, in order to solve some of the above problems, flame retardant synthetic resins have been used as panel fillers. However, this does not solve the conventional problem because it also burns when it fails to extinguish initial fire and reaches near 1,000 ℃. I can't. In addition, to compensate for the deterioration of panel fillers easily, stone, ceramic materials, etc. are used, but they are also strong in heat, but their weight is heavy and the sound insulation and insulation effects are not sufficiently achieved.

In addition, there have been attempts to achieve incombustibility, soundproofing, and insulation by using glass fiber as a panel filler, but glass fiber is adsorbed on the skin or suspended in the air due to fine glass fiber floating in the air during manufacture and installation. There is a problem that the fine glass fiber is continuously discharged from the panel after being sucked into the human body and installed, causing pollution of the human body and the living environment.

In order to solve the problems of the conventional panel fillers, mineral materials such as pearlite are pulverized and foamed, and then inorganic binders are filled and used as panel fillers. However, because the foamed pearlite is combined with the inorganic binder in the form of a pulverized product, its weight is light, but the compressive strength and the tensile strength are weak, and the bonding strength of the fillers is weak, so that the external impact is easily broken.

Therefore, the organic binder is used to increase the bonding strength between the fillers, or the external panel is attached to the outside of the panel filler to increase the strength of the panel, but the organic binder is also composed of an organic compound, The adhesive applied to attach also uses an organic adhesive. In case of fire, the binder for organic filler and the toxic gas emitted when the adhesive for attaching the plate burns may cause a danger of human injury. Since it is separated from the panel filling material, there is a problem that the strength of the building is sharply lowered, leading to collapse.

In addition, since the panel filler and the outer panel have different physical properties such as thermal expansion rate or elastic strain due to external pressure, lateral pressure is applied to the panel due to bending of the building wall surface to which the panel is attached during construction. The panel filler and the outer panel are separated due to the difference in expansion rate due to heat transmitted during the process.

On the other hand, in order to solve this problem, it is also used by adopting an inorganic binder, this binder can prevent the generation of toxic gas to some extent, but there is a disadvantage that it is difficult to form a panel product. As a result, conventionally used building panel fillers provide non-flammable, flame-retardant, tensile strength, compressive strength, flame-retardant adhesives, and do not include all of the functions as eco-friendly materials and solve only a few problems. There is an urgent need for building panels to solve at once.

The present invention was created in order to solve the problems described above, to provide a panel filling material mixed with foamed pearlite, hemp fiber, gypsum powder, and ocher, and to combine the reinforcing cloth inside the panel filling material, the panel filling material Enhance the tensile strength and the compressive strength of each element while having sufficient organic adhesion, and partition the area of the panel filler by the reinforcing cloth to prevent excessive stretching of the panel filler. In particular, when the outer panel is coupled to the outside of the panel filler, when the external panel and the panel filler are stretched or shrunk due to lateral pressure, the external panel and the panel filler are separated from each other by preventing excessive stretching of the panel filler. The purpose is to provide a reinforced non-combustible panel for building.

Building reinforced non-flammable panel according to the present invention for achieving the above object, by pulverizing and heating the pearlite ore to form pores, to cool the pearlite ore formed with the pores and to discharge at a low pressure at high pressure to have additional pores. One foamed pearlite; Hemp fibers in a dried state; Gypsum powder in a dried state; And it characterized in that it comprises a panel filling material which is cured by drying after mixing and compressing the mixed clay containing moisture.

Here, the panel filler is preferably made of a weight ratio of 60 to 80% of the foamed pearlite, 8 to 15% of the hemp fiber, 8 to 15% of the gypsum powder, and 4 to 10% of the ocher.

Here, the inside of the panel filler is preferably extended in the longitudinal direction, it is preferable that the reinforcing fabric is bent in the vertical direction based on the thickness direction of the panel filler.

Here, the thickness of the reinforcing cloth is preferably 0.4mm or more.

Here, it is preferable that a non-combustible outer panel is coupled to at least one side of the panel filler.

On the other hand, another building reinforced non-combustible panel according to the present invention for achieving the above object, by pulverizing and heating the pearlite ore to form pores, by cooling the pearlite ore in which the pores are formed to release at a high pressure at low pressure A panel filler hardened by drying after compressing the foamed pearlite having the additional pores, the dried pulp, the dried gypsum powder, and the yellow soil containing moisture; And a reinforcing cloth provided inside the panel filler and extending in a lengthwise direction of the panel filler and curved up and down based on a thickness direction of the panel filler.

Here, it is preferable that a non-combustible outer panel is coupled to at least one side of the panel filler.

The reinforced non-combustible panel for building according to the present invention has high tensile strength and compressive strength, as well as improves adhesive strength between panel fillers to make a high-strength panel, and combines an external panel to the outside of the panel filler. In this case, when the outer panel and the panel filler is stretched or shrunk by lateral pressure, the reinforcing cloth prevents excessive expansion and contraction of the panel filler, thereby providing an effect that the outer panel and the panel filler are not separated from each other.

In addition, all of the fillers are eco-friendly non-combustible materials, which can prevent the emission of toxic gases in the event of fire, thereby reducing human damage, and preventing the degradation of the thermal insulation and sound insulation functions due to deterioration of panel fillers. Eliminate the disadvantages of contamination.

In addition, it prevents environmental pollution and reduces the cost of disposal. The external panels and panel fillers are glued using environmentally friendly non-flammable adhesives to prevent environmental pollution and prevent toxic gases in case of fire. Do not let it out.

In addition, since the weight is light and easy to carry and install, there is an effect of reducing the carrying and construction costs.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a reinforced non-combustible panel for building according to an embodiment of the present invention, Figure 2 is a perspective view showing the main portion of Figure 1 extracted. 3 is a cross-sectional view of the outer panel is coupled to one surface of the reinforced non-flammable panel of Figure 1, Figure 4 is a cross-sectional view of the outer panel is coupled to both sides of the reinforced non-flammable panel of FIG. 5 is a view schematically showing how the reinforcing cloth is deformed when the lateral pressure acts on the reinforced non-combustible panel for building according to the embodiment of the present invention.

Referring first to Figure 1, the building reinforced non-combustible panel 100 according to an embodiment of the present invention is provided with a panel filler 10, the panel filler 10 is foamed pearlite 12, hemp fiber 14 And gypsum powder 16 and ocher 18 are prepared.

As the expanded pearlite 12, a volcanic stone corresponding to a perlite ore is used. The pearlite is divided into obsidian, pearl rock, pine rock, etc. according to the appearance and volatile components, and is used for the purpose of thermal insulation, heat insulation, sound absorption, and the like, and is widely used as aggregate for filling, mortar, and plaster.

The pearlite forms a myriad of pores, has a small weight to volume, and has low thermal conductivity, thereby providing excellent thermal insulation. In addition, since it is a chemically neutral non-flammable inorganic material, there is no toxic gas generation at the time of fire, and of course, it is suitable as an environmentally friendly material of the present invention because the material is safe enough to be approved for food additive materials.

The hemp fiber 14 is added to increase the tensile strength of the panel filler (10). In general, hemp fiber 14, which is one of natural fibers, has cellulose (Cellulose) as a main component and has a tensile strength of about twice as long as cotton because of its long fiber length. Representative of hemps include linen, ramin, hemp, jute, etc., and any one selected from the above hemps, or a mixture thereof, may be used to achieve the purpose of increasing the tensile strength. Can be. In addition, since the hemp fiber 14 has a long fiber length, the hemp fiber 14 may be cut into an appropriate length and added as one component of the panel filler 10, and preferably about 0.8 mm in diameter.

The hemp fiber 14 may be easily burned because it is a material that burns well, but the hemp fiber 14 is mixed with the foamed pearlite 12, the gypsum powder 16, and the yellow soil 18. When generated, the foamed pearlite 12, gypsum powder 16, ocher 18 is the hemp fiber 14 blocks the contact with the air so that the hemp fiber 14 itself is not directly softened. That is, since the softening of the panel filler 10 starts after about 3 hours even at a high temperature of 800 to 1,200 degrees Celsius, it provides sufficient time to extinguish a fire.

Therefore, by providing a high tensile strength that the panel fillers made of conventional pearlite and inorganic binders do not have, the service life is long and semi-permanent so that the crack does not easily occur due to the difference in humidity according to the irregular ambient diameter or the load or external impact of the building. A panel that can be used is provided.

The gypsum powder 16 is added to increase the compressive strength of the panel filler 10. Gypsum powder (16) is a mineral widely used in various fields because of its wide distribution and low cost. Especially, it is used as a mixture of cement, fertilizer, and white pigment, and used as a calcined gypsum for material, casting model, medical cast, etc. It is also widely used for gypsum board, which is a general building insulation material because it is a thermal insulator.

In addition, when the gypsum powder 16 is used in the form of gypsum board, it is attached to a wall or a ceiling to act as a fire prevention material, and the gypsum board is acoustically absorbent, and a decorative gypsum board coated with printing or plastic coating on the surface thereof. Is used as interior material. In particular, since the gypsum powder 16 has a large compressive strength, when the gypsum powder 16 is used as a filler of the reinforced non-combustible panel 100 for building according to the present invention, the gypsum powder 16 has a function of distributing the load of the building to prevent breakage of the panel due to external load.

Meanwhile, vermiculite, which has various uses as a soundproof material, a heat insulating material, a heat insulating material, a lightening material, a soil improving agent, and a soil coating, may be used instead of the gypsum as a heat resistant material. That is, by making the vermiculite powder provide the same compressive strength provided by the gypsum, it is possible to diversify the material used.

Of course, since the vermiculite has a plurality of pores and expands at a high temperature, it is preferable to first heat it to a high temperature and expand it to form a powder to be processed to have a high compressive strength. Like gypsum, it is possible to provide high density compressive strength.

The ocher 18 is a well-known fact that it blocks harmful waves such as water veins and emits far-infrared rays, which are beneficial to the human body. Therefore, when used as a filler does not generate harmful substances, there is an advantage that there is no problem of environmental pollution when the panel filler 10 is disposed of.

In particular, the ocher 18 has a strong adhesive strength when mixed with other fillers in the state containing a small amount of water and dried. Thus, the ocher 18 serves as an adhesive of the panel filler 10 according to the present invention. At this time, since the ocher 18 is dried in a plurality of pores formed in the foamed pearlite 12, it provides a strong adhesive force in a mixed state with the foamed pearlite 12, hemp fiber 14, gypsum powder 16. .

2 to 4, the reinforced non-combustible panel 100 for building according to the present invention includes a reinforcing cloth 20 and a non-combustible outer panel 40.

When the external pressure is applied to the panel filler 10, the reinforcing cloth 20 prevents cracking of the panel filler 10, and in particular, the non-combustible outer panel 40 is disposed outside the panel filler 10. When combined, it is provided to prevent separation of the non-combustible outer panel 40 and the panel filler 10.

The reinforcing cloth 20 is coupled to the inside of the panel filler 10 and extends in the longitudinal direction of the panel filler 10. In addition, the reinforcing fabric 20 is bent in the vertical direction based on the thickness direction of the panel filler (10). That is, as shown in Figures 1 and 2, the reinforcing cloth 20 is extended in the longitudinal direction of the panel filler 10 while having a wavy shape of a wave.

In this embodiment, since the reinforcing fabric 20 is bent and extended in the vertical direction, the panel filler 10 is partitioned into a plurality of regions. That is, as shown in Figure 5, the panel filling material 10 is partitioned by the reinforcing fabric 20 adjacent to each other. For example, FIG. 5 illustrates a portion of the region of the panel filler 10 partitioned by the reinforcing fabric 20 as the first region A1 and the second region A2.

In addition, in this embodiment, the thickness of the reinforcing cloth 20 is used that is 0.4mm or more. When the panel filler 10 is stretched due to external lateral pressure, the reinforcing cloth 20 is stretched together with the panel filler 10 to prevent the non-combustible outer panel 40 and the panel filler 10 from being separated.

The non-combustible outer panel 40 is provided on at least one side of the panel filler 10. 3 illustrates a state in which the non-combustible outer panel 40 is attached to one surface of the panel filler 10, and FIG. 4 illustrates a state in which the non-combustible outer panel 40 is attached to both sides of the panel filler 10. do. When the non-combustible outer panel 40 is attached to only one surface of the panel filler 10, the attached surface may be used as an outer or inner surface of the building, and the non-combustible outer panel 40 may be formed on both sides of the panel filler 10. When attaching, since both sides can be utilized as an exterior and an attachment surface of the building, the non-combustible outer panel 40 may be selectively attached to one or both sides of the panel filler 10. In addition, there is sufficient strength even when the non-combustible outer panel 40 is provided on only one side, but by attaching the non-combustible outer panel 40 to both sides, the reinforced non-combustible panel 100 for building can be used with higher strength. It can be produced selectively according to the place to be. In addition, although the material of the non-combustible outer panel 40 is preferably made of a metal material, other materials may be manufactured.

In the present embodiment, the non-combustible outer panel 40 is attached by the non-combustible adhesive 30. The non-combustible adhesive 30 is prepared by mixing magnesium oxide (MgO), magnesium chloride (MgCl 2) and dibasic sodium phosphate (Na 2 HPO 4) in a weight ratio of 4: 4: 2.

The magnesium oxide is produced in the form of a solid powder by heating metal magnesium in air or pyrolyzing magnesium carbonate. In particular, it is generally used as a refractory material, crucible, magnesia cement, catalyst, and adsorbent, and it is a compound of magnesium and oxygen that absorbs water and carbon dioxide from the air, and has various uses such as refractory materials, catalysts, adsorbents, antacids and adhesives. .

In addition, the magnesium chloride has a liquid form with a compound of chlorine and magnesium, has a strong hygroscopicity, and has a property of being well soluble in water and alcohol. It is used in many fields, such as tofu coagulants, wood preservatives, the manufacture of parchment paper (sulfur), and the refining of wool.

In addition, the dibasic sodium phosphate is prepared by reacting the dilute phosphoric acid solution with sodium carbonate to concentrate and precipitate crystals at 35 ° C. or below, and prepared in powder form. It is also colorless to white crystalline and has the property of being easily soluble in water and insoluble in alcohol.

In this case, when the magnesium oxide and magnesium chloride alone are mixed and used as an adhesive, the magnesium chloride is in a liquid phase, so the particles are protruded to the outside of the magnesium oxide so that the coated surface is irregular and uneven. Therefore, the second sodium phosphate may be added to form an even surface by filling an irregular surface. In addition, the sodium diphosphate is often heat-resistant enough to be used as a spray of the fire extinguisher, the magnesium oxide and magnesium chloride acts as a strong adhesive, the dibasic sodium phosphate acts to cool the high temperature Since the adhesive does not melt even at a temperature near 1000 ° C. in the fire, the panel filler 10 and the non-combustible outer panel 40 are prevented from being separated.

Therefore, in case of fire, the adhesive 30 is easily melted, so that the panel filler 10 and the non-combustible outer panel 40 are separated to prevent an accident that collapses due to weakening of durability of the building, and it is toxic by using a flame retardant material. It is possible to prevent personal injury due to the generation of gas.

In addition, although not shown in the drawings, the adhesive 30 is applied to one or both sides of the panel filler 10, and then the non-combustible outer panel 40 is attached thereto, and further fastened by means of bolts, screws, rivets, and the like. The bonding force of the non-combustible outer panel 40 can be further increased. In addition, a method of compressing and attaching the non-combustible outer panel 40 to one surface or both surfaces of the panel filler 10 may be used.

Hereinafter, the manufacturing process and operation of the building reinforced non-combustible panel 100 according to the present invention by the above configuration.

First, the pearlite ore is crushed and the pulverized product is subjected to a heating process for a predetermined time to 900 ~ 1200 ℃ and then undergoes a cooling process. At this time, a plurality of pores are formed in the pearlite pulverized itself and is heated and cooled to a high temperature, thereby making foamed pearlite 12 having a plurality of high pores and high strength.

Next, by rapidly releasing the pulverized foamed pearl 12 having a plurality of pores formed from a high pressure state to a low pressure state, the foamed pearlite having more pores than the pores formed in the heating step by forming additional pores between the pearlite particles ( 12) is made.

As described above, the reason why a large number of pores are formed is that the pearlite gemstone contains 3 to 4% of volatile components, and when the pearlite having such properties is finely pulverized and suddenly heated, the volatile components contained therein expand inside. The internal pores are formed to expand about 10 to 20 times the original volume and has a light specific gravity.

Next, the mixture is mixed in a weight ratio of 60 to 80% of the foamed pearlite (12), 8 to 15% of hemp fiber (14), 8 to 15% of gypsum powder (16), and 4 to 10% of ocher (18). Make. At this time, since the loess 18 contains a small amount of water, even if the hemp fiber 14 and the gypsum powder 16 are dried, there is no problem in uniform mixing.

The reason for containing water only in the ocher 18 is because it is more difficult to uniformly mix the viscous hemp fiber 14 and the gypsum powder 16 and the ocher 18 with each other. This is because it is easier to sprinkle and mix the expanded pearlite 12, hemp fiber 14, and gypsum powder 16 on the viscous ocher 18 containing a small amount of moisture. In addition, the soil-containing ocher 18 functions as an adhesive, thereby preventing deterioration of the hemp fiber 14 and the gypsum powder 16 due to moisture content, thereby preserving the properties of the raw materials.

Of course, the foamed pearlite 12, hemp fiber 14, gypsum powder 16, ocher 18 may be mixed with water, but the ocher 18 preferably contains water.

Next, after inserting the reinforcing cloth 20 into the mixture containing water and compressing it into a mold to make a panel shape, and then passing through a heater to evaporate the moisture contained in the mixture, the panel filler in the hardened state (10) Is made.

At this time, since the panel filler 10 made of the mixed hemp fibers 14, gypsum powder 16, ocher 18 is compressed and molded into the pores of the foamed pearlite 12 and then dried, the foamed pearlite 12, hemp fibers 14, gypsum powder 16, and loess 18 are strongly bound to each other to further increase the bonding force. In addition, even without a separate binder for the panel filler 10 may be provided with a sufficient bonding force by the adhesion of the pores of the expanded pearlite 12 and the ocher 18.

As a result, the panel filler 10 is compressed and bonded with a large force, and the hemp fiber 14, the gypsum powder 16, and the loess 18 have an organic relationship with each other and have a long-lasting characteristic. The hemp fibers 14 added to the panel filler 10 provide a high tensile strength, the gypsum powder 16 provides a high compressive strength, and the loess 18 provides a strong adhesive force, which is environmentally friendly. It becomes a reinforced non-combustible panel 100 for building having a high strength.

Next, the non-combustible adhesive 30 is applied to the outer surface of the panel filler 10, and the non-combustible outer panel 40 is attached thereto. The non-combustible outer panel 40 may further increase the protection and strength of the panel filler 10.

Of course, as shown in Figure 1, since the panel filler 10 has sufficient strength in itself, it can be used as a reinforced non-combustible panel 100 for building only by the panel filler 10 according to the purpose and environment of use. Reveal.

When the external lateral pressure acts on the reinforced non-combustible panel 100 for building according to the present invention manufactured as described above, the function and action of the reinforcing cloth 20 will be described in detail with reference to FIG. 5.

FIG. 5 schematically shows the deformation of the reinforcing cloth 20 when the external transverse pressure is applied in the state where the non-combustible outer panel 40 is attached to both outer sides of the panel filler 10. Specifically, the state in which the lateral pressure (P) acted in the direction of tensioning the reinforced non-flammable panel is shown.

When the lateral pressure P acts in the direction of tensioning the building reinforced non-combustible panel 100 according to the present invention, the lateral pressure is applied to each region of the panel filler 10 partitioned by the reinforcing cloth 20. For convenience of explanation, the lateral pressure acting on the first region A1 which is a part of each region of the panel filler 10 partitioned by the reinforcing cloth 20 is called P1, and the lateral pressure acting on the second region A2 is It is called P2.

Since the lateral pressures P1 and P2 act on the first region A1 and the second region A2 partitioned by the reinforcing fabric 20, the reinforcing fabric 20 partitioning the first region A1 and the second region A2. The parts of) are forced to contract each other. If the lateral pressures P1 and P2 have the same magnitude, the first area A1 and the second area A2 are stretched by the same length. Since the reinforcing cloth 20 has a thickness of 0.4 mm or more, the first area A1 and the second area A2 are stretched by half of the thickness. When the first region A1 and the second region A2 are tensioned, forces in opposite directions act at the boundary portions of the first region A1 and the second region A2 so that the reinforcing fabric 20 contracts. do. That is, the reinforcing cloth 20 maintains the state shown by the imaginary line L1 before the lateral pressure P is applied, and when the lateral pressure P is applied, it is contracted as shown by the solid line L2. Thus, the boundary between the first area A1 and the second area A2 is tensioned in the opposite direction to prevent excessive tensioning. In the present embodiment, the thickness of the reinforcing fabric 20 is used more than 0.4mm, when the thickness of the reinforcing fabric 20 is less than 0.4mm, the tension of the panel filler is excessively limited when the lateral pressure to tension the panel filler. Therefore, it is not preferable.

As a result, each region of the panel filler 10 partitioned in the reinforcing fabric 20 by the above process is finely tensioned, the boundary portion of each region has a limit in the degree of tension by the reinforcing fabric 20, Even if excessive lateral pressure is applied to the panel filler 10, the panel filler 10 is prevented from being excessively tensioned by the reinforcing cloth 20, thereby preventing the panel filler 10 from being separated from the non-combustible outer panel 40.

In addition, when vertical pressure is applied in a direction in which the panel filler 10 is bent, for example, in a direction perpendicular to one surface of the panel filler 10, the reinforcing cloth 20 prevents cracking in the panel filler 10.

As such, the building reinforced non-flammable panel 100 according to the present invention has the characteristics that the hemp fiber 14, gypsum powder 16 and the ocher 18 has an organic relationship with each other and endures at high temperatures for a long time, and has high tensile strength. As well as having strength and compressive strength, the bonding force of the panel fillers 10 is improved to provide a high strength panel.

In addition, when the external lateral pressure is applied to prevent the separation of the panel filler 10 and the non-combustible outer panel 40 by the reinforcing cloth 20, even if pressure is applied in the direction in which the panel filler 10 is bent 10 of the panel filler 10 Prevents cracking

In addition, since the panel fillers 10 are environmentally friendly non-combustible materials, it is possible to prevent the emission of toxic gases in the event of fire, and to prevent degradation of the thermal insulation and sound insulation functions due to deterioration of the panel fillers 10, and pollution of the human body and the living environment. This disadvantage can be eliminated as well as preventing environmental pollution during disposal, and can reduce the cost of disposal. In addition, since the outer panel and the panel filler are bonded using an environmentally friendly non-flammable adhesive, it prevents environmental pollution and does not emit toxic gases in case of fire.

On the other hand, in the building reinforced non-combustible panel 100 according to the embodiment of Figure 4, instead of the hemp fiber 14, pulp can be used.

The pulp is added to improve the tensile strength of the panel filler 10 like the hemp fiber 14. In general, the fiber length of the pulp is 0.1mm ~ 0.4mm, shorter than the fiber length of the hemp fiber 14, the tensile strength improvement is small compared to the hemp fiber 14, it can be used to replace the hemp fiber (14).

The pulp is a collection of cellulose fibers obtained by mechanical, chemical or intermediate methods from wood or other fiber plants, and pulp such as stems of rice plants and hemp stems, bark such as hemp, stems other than branches and leaves of trees. There are many kinds of can be added selectively depending on the application range and application.

In addition, when the pulp is classified according to the raw materials, wood pulp and non-wood pulp is divided into, coniferous pulp (NP), leaf pulp (LP) is divided again, the non-wood pulp is straw pulp (straw pulp) ), Bagasse pulp, reed pulp, bamboo pulp, bast fiber pulp, rag pulp, cotton pulp, and the like, in the present embodiment, the above-described various types may be selectively used.

Particularly, when the pulp is used as the panel filler 10, the panel filler 10 may be given a unique tensile strength, and the weight of the pulp itself may be light, thereby making the panel filler 10 lightweight.

On the other hand, the pulp may be easily burned because it is a material that burns well, but when the fire occurs, the foamed pearlite 12, the gypsum powder 16, and the loess 18 are mixed with the pulp. (12), the gypsum powder 16 and the loess 18 prevent the pulp from directly softening because the pulp blocks contact with air. That is, since the softening of the panel filler 10 starts after about 3 hours even at a high temperature of 800 to 1,200 degrees Celsius, it provides sufficient time to extinguish a fire.

Therefore, high tensile strength is also provided by the pulp in place of the hemp fiber 14, so that the crack does not easily occur due to the difference in humidity according to the irregular surrounding diameter or the load or the external impact of the building, so that the service life is long and semipermanently. It can provide a panel that can be used.

As mentioned above, although this invention was demonstrated in detail about the preferred embodiment, this invention is not limited to the said Example, A various many deformation | transformation may be provided within the range which does not deviate from the scope of the present invention. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
